Abstract: A tool head for use in machine tools, has a main body which can be rotated around an axis of rotation. The tool head has a slide. The slide can be moved by means of a pull rod axially oriented in the main body. The slide can be fitted with at least one tool or one tool holder. At least one adjustable toothed plate is fixedly arranged on the slide. The toothed plate has a helical gearing functioning as a gear means for engaging with a helical gearing of the pull rod which is complementary thereto. The slide has an adjustment unit for moving the at least one toothed plate and the helical gearing thereof into the complementary helical gearing of the pull rod.

Abstract: A tool head for use in machine tools comprising a base body coupled to a machine spindle, comprising at least one tool-receiving means for a cutting tool, and comprising a rotatable slide mechanism, which eccentrically carries the tool-receiving means, and is rotated about an eccentric axis parallel to the base-body axis with respect to the base body in order to facilitate an adjusting of the cutting radius of the cutting tool. A second rotatable slide mechanism is provided which carries a second eccentric tool-receiving means, and is rotated about a second eccentric axis parallel to the base-body axis with respect to the base body in order to facilitate an adjusting of the cutting radius of the respective cutting tool. Furthermore, transmission means is arranged in the base body to facilitate a simultaneous driving of the two rotatable slide mechanisms.
